The active POE splitter from Laird Technologies gives "carrier class" performance in a low cost system. With its IEEE 802.3af compatibility and advanced auto-sensing algorithm it will accept POE power from any IEEE 802.3af router or power supply.

The overload and short circuit protection will shut down power immediately when a short circuit is detected without any damage to the POE system. Power (36 to 60V) is expected on ethernet pins 4/5 (V+) and 7/8 (V-) as per the IEEE 802.3af standard or pins 1,2,3,6 (Cisco Standard).

Using power over ethernet to power remote devices has several advantages including:

The power supply can be centrally located where it can be attached to an uninterruptiblepower supply.

Power can be supplied over long distances, up to 300 feet

Power can be available wherever network access is available

The user has the ability to easily power on reset the attached equipment from a remote location

The active POE splitter from Laird Technologies can be used by the original equipment manufacturer to supply power to remote equipment and devices without the expense of building in separate POE functionality into their equipment. These devices are a good fit for the industrial market for sensing and remote video applications.
